.SPEGIFIGATION formingpart of Letters Patent No. 730,449, dated June 9, 1903.

Application filed. Apr-i111, 1902 To all whom it, may concern.-

Be it known that I, LELAND L. Foss, a citizen of the United States, residing at Manassas,in the county of TattnalLState of Georgia, have invented certain new and useful Improvements in Roller-Grins; and I do hereby declare the following to he a full, clear, and exactdescription of the invention, such as will enable others-skilled in'the art to which it appertains to make and use the same.

This invention relates to cotton-gins of the roller class, which are designed to draw the cotton from the seeds or loosen the seeds from the fiber and push or crowd them out of the same to free the lint from the seeds without tearing or breaking the fibers of the cotton. I The invention has for its chief object the acting or so constructed as to increase its operative capacity to a double degree, and one form of means'in which I have embodied the invention, as exemplified in the specification, includes laterally-spaced rollers, in cotiperative relation to which are disposed ginningblades,while between the rollers are arranged cooperative sets of hackers mounted for alternate movementtoward and away from their respective rollers and ginning-blades, whereby the cotton will be ginned at both sides and will be thoroughly cleansed and the seeds discharged through the seed-boards, which are arranged in position to recei've the cotton and support it in proper position for ginning.

A further object of the invention is to pro-' vide means for adjusting the movements of the hackers and for adjusting other portions of the mechanism to secure the best results under different conditions and also to pro vide a construction that may be embodied in either a long gin or a short gin, the long gin being substantially a duplication of the short gin.

Other objects and advantages of the invention will be understood from the following description. i

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a perspective view of my improved gin, one of the discharge-chutes Serial No. 102,472. (No model) being removed to show the mechanism for actuating the hackers. Fig. 2 is a plan view of the gin. Fig. 3 is an end elevation of the gin. Fig. 4 is a transverse section through the gin. Fig. 5 is a vertical section taken longitudinally of the 'gin.

The drawings as well as they portray wellknown forms of mechanism and essential well-known means are diagrammatic in contradistinction to what are known as working drawingsg but they are designed to picture the invention so that any one skilled in the art may make and use the same, it being understood that in practice various modifications of the specific construction shown may be made and that any suitable material and proportions may be used'for the various parts or their equivalents without departing from the spirit of the invention.

Referring now to' the drawings, there is shown therein a long or double gin, including two sets of hackers, two seed-boards, and accompanying members, the breasts'and rollers at the opposite sides being long enough to accommodate the two sets of hackers which operate between the seed-boards and the rollers. The gin comprises a framework including, as herein shown, for example, longitudinal sills and 11, which are connected by means of the end sills l2 and 13 and the intermediate transverse sill 14'. Upon the sills are disposed the corner-uprights 15, 16, 17, and 18, and upon the upper ends of which are secured the top beams 19 and 20, respectively, below and parallel with whichare the transverse supporting-beams 21 and 22, between which and the top beams are disposed the bearingboxes for the breasts, stay-bars, and feedershaft. Extending longitudinally of the ginframe and at opposite sides thereof are the breasts 25 and 26, at the ends of which are trunnions 27, which turn in and project boxes and therewith the breasts or to permit them to drop. Against the inner faces of the breasts are bolted the ginning-blades 31, these blades extending throughout the length of the breasts and projecting slightly therebelow, as shown. Upon the beams 21 and 22 are bearing-boxes 32 and 32, and upon the central intermediate cross-beam 14 of the frame of the gin isa post 33, on which is a third bearing 34. Two stay-bars 35 and 36 are provided, having trunnions at their ends, said trunnions of each bar being shown at 41 and 42, formed upon the blocks 39 and 40, to which are secured two parallel spaced plates 37 and 38, the platesof each stay-bar being connected at intervals by the bolts 43, which hold them firmly against the block. The stay-bars support the hacker-plates,which are sustained from the stay-bars by means of the bolt-bars 51, which are engaged with the side plates of the stay-bars and the lower portions of the hacker blades or plates 31, the boltbars having nuts engaged therewith to hold them inplace. The lengths of the bolt-bars are such that the hacker blades or plates are held in positionfor movement into contact with the ginning-blades when the stay-bars are oscillated, and to permit of adjustment of the paths of movement of the hacker blades or plates the bearing-boxes of the stay-bars are arranged to be adjusted vertically. To provide for vertical adjustment of the bearing-boxes of the stay-bars, they are slidably mounted between angle-irons 53, which are secured in pairs upon the beams 21 and 22 and the post Between each pair of angleirons and beneath each bearing-box is arranged a wedge 55, which when moved in one 4 direction will force the bearing-box upwardly and when moved in the opposite direction will permit it to drop, and to shift these wedgeblocks simultaneously they are connected to a shift-rod 56, which is passed therethrongh, one end of the shift-rod being threaded and passed through the yoke-plate 57, which is secured against the outer face of the beam 21, the threaded portion of the rod having a hand-nut 58 engaged therewith to draw the rod through the yoke-plate and hold it against movement. The wedges work directly against wear-plates 54 at their under sides, and it will be noted that the bearing-blocks are formed in sections and are provided with Babbitt linings 53.

Upon the beams 21 and 22 are the blocks 59, one of which is adjacent to the inner face of each end of each ginning-blade, so' that the blocks are in pairs longitudinally of the gin, and upon each pair of blocks is disposed aslotted metallic seed-board 44, the end portions of the seed-boards being slotted transversely toreceive bolts 45, that project upwardly from the blocks 59, and with which bolts are engaged nuts 46, so that the seed-boards may be moved toward and away from the planes of the ginning-blades and may be clamped in their adjusted positions. The hacker plates or blades operate beyond and in close proximity to the outer edges of the seed-boards and move first above and then below the seed-boards, and the two sets of hacker-plates, when the machine is constructed in double form, are preferably reversely operated-that is, when a hacker-plate of one set at one side of the gin is moving upwardly the plate of the other set at the same side of the gin is moving downwardly. T0 effect this movemeut of the hacker-plates, a single crankshaft is provided and in connection with which crank-shaft is shown two different forms of means for transmitting motion to the sets of hackers. It will be noted that one set of hackers has two V-shaped frames 61, bolted with their free ends to the end portions of angle-irons, which are riveted in turn against the inner faces of the hacker-plates at opposite sides of the gin, these frames being converged downwardly and having their bights 62 bent into cylindrical form to receive a pin 53, which may be termed a coupling-pin, and the end portions of which pin are threaded to receive nuts 64 and 65, engaged at opposite sides of each bearing, and between the nut 65 is the strap 66 at one end of a pitman 67, the pitman at its opposite end having the usual bearing between its extremity and the block 68, held thereagainst by the strap 69, and in which bearing is received the crank 70 of the crank-shaft 71,

- mounted in bearing 72 on the transverse sills and intermediate beams. The lower portions of the sides of each frame 61 are parallel, and between them are riveted the lower ends of bars 73, the upper ends of which are engaged with clam ping-plates 74, disposed against the upper and lower edges of the side plates of the stay -bar, the bars 73 having nuts 75, which hold the plate 74 in position. With this construction it will be seen that when the shaft 71 is rotated the stay-bar is rocked to reciprocate the hacker-plates. In connection with the other set ofhacker-plates there are shown two pitmen 76, which are engaged with the two cranks 77 of the shaft 71, the straps 78 at the inner ends of the pitmen being bifurcated and engaged with the long pin 79. Connected with each end of the second set of hacker-plates are the upper ends of a V-shaped frame 80, the bight portion of which (shown at 81) is bent to form a bearing in which the pin 79 is received, the two V-shaped frames being substantially vertical instead of convergent, as in the firstinstance. Riveted between the lower portions of the sides of each frame 80 are the lower ends of bars 81, the upper ends of which are engaged with plates 82, corresponding to the plates 74, and which plates are held in place by nuts 83, engaged with the bar. It will be noted that the cranks 77 project at the opposite side of the shaft from the crank 70, so that the two sets of hacker-plates are operated in opposite directions.

Upon the beams 21 and 22 are mounted ad- IOC 'upon the chute 91.

' hacker-plates, so that the cotton that is placed upon the seed-board will come in contact with the rollers and will be drawn thereby between the plates and blades. As the seeds move with the cotton against the rollers they are in position for contact by the hacker-plates,

' which move them against the ginning-blades;

so thatthere is a hitingor nibbling action of the blades and plates,with the result that the cotton is taken from the seeds or, rather,the seeds are loosened from the cotton and pushed out of it, the cotton passing outwardly with the rollers, from which it is dofied and discharged The seeds as they are freed from the cotton fall upon the seedboard, from which they pass through the openings therein. In. order that the ginningblades may be adjusted in their relation or proximity to the rollers, the breasts are pivotally mounted, as above described, in the vertically-adjusted boxes, which boxes are held yieldably in lowered position by the springplates 92, which are disposed with their ends upon the trunnions of the breasts and are arched upwardly, set-screws 93 being engaged with the plates 94, that project from the beams 19 and 20, the lower ends of the screws bearing upon the central portions of the plates, and by adjusting these screws the tensions of the plates may be varied. To hold the breasts yieldably against pivotal movement and at the same time to adjust them with respect to the rollers, plates 95 are secured upon the upper faces of the breasts, and through perforations in the upper ends of the plates is engaged a tension-bolt 96, provided with an adjusting-nut 97, by manipulation of which the breasts may be swung, withthe ginning-blades, against the rollers to secure the proper pressure of the blades against the rollers. By this means the proper adjustment of the blades is secured throughout their lengths, so that nipping of the rollers is prevented. Thus both blades are given the same pressure against the rollers. Furthermore, it will be noted that each blade has one clamp 98,which holds it against the breast.

Between the ends of the frame of the gin and below the upper beams thereof is disposed a double shed 99, the ridge of which is directly above the stay-bars and the side edges of which project over the seed-boards, so that cotton depositedupon the shed will pass downwardly into position for engagement'and treatthat when one is moved from under the shed up to the adjacent hacker-plate, the other beam will be drawn under the shed. To reciprocate the feeding-beams,a crank-shaft 102 is mounted in boxes between the upper portions of the angle-irons 53, between which the stay-bar boxes are mounted, the boxes of the crank-shaft being shown at 103 and the shaft extending longitudinally throughout the length of the gin. With the cranks of the crank-shaft are connected. pitmen 104, connected also with one'of the beams 100, as shown. Thus as the crank-shaft is rotated the feeding-beams or feeder is actuated. The crank-shaft is provided with pulley-wheels 105 and 106, and connecting the pulley 105 with a pulley 107 on the roller 89 is a belt 108,

while a belt 109 connects the pulley 106 with a pulley 110 on the roller 90, the second mem ber of the pulley 106 being adapted to receive a driving belt for operating the machine. The roller 89 has also a pulley 111, with which is engaged a belt 112, leading to a pulley 113 on the crank-shaft 102 for operatingthe latter.

In the construction of a single or short gin only a single set of hackers is employed, the

breasts and rollers being correspondingly shortened.

The arrangement of the driving means is such that both rollers are rotated with their sides to the seed-boardsin the same direction.

In all instances the arrangement is such that in the supplying of cotton to the machine a single hopper only is required to be watched. Furthermore, it is to be noted that the ginrollers are arranged in the same horizontal plane and at the outersides of the seed-boards, so that the operation of the parts can at all timesbe observed and everything he kept going in proper order. position of the several parts of the machine is such that the strain on the machine is equalized, and it is quite as easily operated and tended or its operation observed. as though there were one roller and adjuncts employed, while its capacity is substantially double.
